Self Activation with Comcast/Xfinity Voice and Internet Arris TM822G Modem

Arris _TM822G

This new year resolution was to replace the 5 year old rental Arris TM722G from Comcast with a used/new/refurbished one from an Amazon seller for $65. I was skeptical about the compatibility and activation since I have both voice and internet with them. The instruction for self activation was amazingly accurate and easy to do.
